据胡秀英《泡桐属专著》记载,1949年J.Westfall发表了一篇泡桐染色体数目,他确定毛泡桐的染色体数目为2n=40,但这篇文章全文未见出版.近几年来,国内外林木育种工作者,虽多次对泡桐染色体进行观察研究,也未见正式发表文章,故泡桐体细胞染色体确切数目都没有定下来.正确地掌握泡桐不同种类的染色体数目,对深入研究泡桐的植物学分类,指导泡桐育种,了解遗传变异规律是十分必要的.为此,我们选用了白花泡桐(Paulownia fortunei (Seem) Hemsl.)、楸叶泡桐
According to Hu Xiuying << Paulownia monograph >> records, J.Westfall published a number of Paulownia chromosomes in 1949, he determined Paulownia chromosome number 2n = 40, but the full text of this article has not been published in recent years, both at home and abroad Breeding workers, although many paulownia chromosomes were observed and studied, and no official published articles, so the exact number of somatic chromosomes of Paulownia are not set down correctly grasp the different types of paulownia chromosome number, in-depth study of Paulownia Botany It is very necessary to classify and guide Paulownia breeding and understand the genetic variation rules.Therefore, we selected Paulownia fortunei (Seem) Hemsl.),
